I got a tilt recently and this is my first full brew using it. I actually threw it in on my last beer but when it came in the mail fermentation was complete so it just sat at FG for a few days and wasn't very exciting. I'm an engineer (nerd) and was excited about getting data more often and being able to not open the fermenter to take readings. I'm a bit surprised by the data though.
Bit of background. This is a pretty simple blonde ale I brewed to experiment with a few process things (first time kegging and new to being able to control fermentation temps). Grain bill is mostly xtra pale ale and golden promise with a bit of wheat, flaked barley and honey malt. Liberty hops all in the boil. I had a bit of an issue on brew day and ended up going over my OG target and was at 1.057 measured by hydrometer (not sure the issue, but I think I measured preboil gravity without letting the wort cool and then adjusted with DME - I swear I let it cool but that's the only explanation I have). Yeast is Lalbrew Verdant. I ferment in a glass big mouth bubbler in my basement.
Note I do not have the tilt connected to anything real time yet so readings happen mostly morning and evening when I am near by and check in with my ipad.
It seems like there is an offset in the Tilt vs my hydrometer. That part I'm not too worried about since I'm more interested in the data trend/when it finishes then the absolute number. I can always take a hydrometer reading once the tilt shows fermentation has settled out. The beginning trend makes sense to me. Gravity drops and temperature rises. Fermentation was very active during this stage. Then as the fermentation slowed down the temperature dropped. Question 1 would be I'm not sure why SG increased a bit as the temperature dropped.
I mentioned I'm also using this batch to play around with some new temperature control equipment. I have a ferm wrap I turned on April 12th where the temp increases connected to an InkBird. I decided to try that out to hold a higher temperature for things to clean up. You can see at first I had a pretty wide band of the temperature hysteresis (hadn't changed the default) so temperature was cycling about 3 degrees. I've since narrowed that up some which you can see in the data. From the data though it appears that the SG is changing somewhat inversely with temp. I wouldn't be surprised to see a bit of noise in the data, but the swings are close to 10 points. Anyone else seen this?
One other note I did have a point the night of April 11 that the fermentation was strong enough the lid popped up and puked krausen down the side of the FV (kraused plugged the blow off hose). Not sure why that would have an effect but wanted to mention it.
